In my application we need to upload a document which will connect to a different system to send the document content.

Connect Rest has been configured which is a multipart form. But the xternal system is expecting the docuent content as a file :

                        // This attaches the file to the POST:
                        File f = new File(filepath);
                        builder.addBinaryBody(
                                                "docContent",
                                                new FileInputStream(f),
                                                ContentType.APPLICATION_OCTET_STREAM,
                                                f.getName()
                                                );
But PEGA is supports only base64.

Is there any option available where i can send teh actual file through connect rest.
